MOF-derived Carbon-based Electrocatalysts Confinement Catalyst on O2 Reduction and CO2 Reduction Reactions

The massive consumption of fossil fuels and the gradual deterioration of the environment urgently require the development and exploration of effective energy conversion and storage technologies. Electrochemistry is the basis and key of all kinds of energy storage and conversion devices. The design and synthesis of non-noble metal-based and non metal-based catalysts with high catalytic activity are obviously the best choice. The metal organic framework （MOF） derived carbon-based materials have the characteristics of large specific surface area and high porosity， which can selectively confine metals of different types. Therefore， MOF has a good confinement effect when used as a catalyst， which is beneficial to improve the activity and stability of the catalyst. In this review， the confinement effects of MOF-derived materials in catalytic reactions are clarified， and the latest progresses of MOF-derived carbon-based materials in oxidation reduction reaction（ORR） and CO₂ reduction reaction（CO₂RR） electrocatalysis are introduced， and the structure-activity relationships of MOF-derived carbon-based materials in electrocatalytic reactions are revealed. Finally， the challenges and opportunities faced by MOF-confined carbon-based materials in ORR and CO₂RR electrocatalysis are discussed， as well as the possible solutions in the future.
